{"version":"1.0","type":"rich","title":"D3 World Population Area Chart","description":"This visualization combines an area chart with D3’s `scaleTime` and `scaleLinear` to show world population growth from 1960 to 2015, using a smoothed `curveBasis` path. It loads CSV data via `d3.csv` and formats y-axis ticks with `format('.1s')`. The SVG render includes labeled axes with gridlines from `axisBottom` and `axisLeft`, while the maroon-filled area emphasizes population magnitude over time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e89b3f2941a4832926339f43c0278f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
